The ultra-deep-water semi-submersible drilling rig "Blue Whale II", which can mine both combustible ice and oil, is pictured at a harbour in Yantai city, east China's Shandong province, 28 July 2017. The construction of the ultra-deep-water semisubmersible drilling rig Blue Whale II, which can mine both combustible ice and oil, will start a 21-day trial run, according to its manufacturer. China Yantai CIMC Raffles Offshore Ltd, the producer of the Blue Whale 1, succeeded in collecting methane gas trapped in ice-like crystals beneath the surface of the South China Sea last week. It said the functions of the Blue Whale 2 will be slightly different from the first model in terms of flammable ice drilling. Combustible ice, a particular kind of natural gas hydrate usually existing in seabed or tundra areas, is formed under strong pressure and low temperatures. It is regarded as a clean energy option with high energy density and huge reserves.
